Hardware event priority sensitive programmable transmit wait-window for virtual GPIO finite state machine

摘要

Systems, apparatus, methods and techniques that can provide optimized low-latency communications between different devices such that GPIO signals may be carried as virtual signals. A virtual GPIO finite state machine in a first device is provided that can consolidate GPIO-related events by initiating a wait period after a first-occurring event and that has a duration selected to permit one or more later-occurring events to be detected before transmission of virtual GPIO data over a data communication bus to a second device. One method may include initiating a wait period after detecting a first change in GPIO state, refraining from transmitting virtual GPIO data during the wait period, detecting occurrence of a second change in GPIO state during the wait period, and transmitting virtual GPIO data corresponding to the first and second changes in GPIO state over the serial bus after the wait period has expired.
